Allow path traversal in file explorer

[SachsKaylee]

Hello there!

I stumbled upon Jodit a few days ago and it seems like a really awesome editor. I didn't expect this from a library that isn't hugely popular.

However I didn't like an aspect of the file browser: I can only move forward, not backwards(e.g. a folder path like ..).

This way I can write code like this in my backend, adding a .. back option for all non-root paths:

return res.sendData({
      data: {
        success: true,
        time: new Date().toISOString(),
        data: {
          messages: [],
          sources: {
            [source]: {
              path: path,
              baseurl: "/api/files/serve/",
              folders: split.length ? ["..", ...dirs] : dirs
            }
          },
          //  ....
        }
      }
    });

Am I misunderstanding how the filebrowser should be used or is a "go to parent folder" like functionality currently missing from the file browser?

It was also impossible to upload files without extension, e.g. "my-file" - I took the liberty to fix this. It is perfectly normal for files to not have an extension on Unix platforms.

Files are now uploaded even if they do not have an extension.
